HD Tune Pro gives us accurate read, write and access time results and for the last couple of years has been gaining popularity amongst reviewers. It is now considered a must have application for storage device testing.

To date most of the MP2 firmware drives we tested lost a little performance in retail form, but the S599 doesn't lose performance like the others. Since the S599 is the latest drive we tested it would appear that the newest firmware revision has cleared some of penalty up a bit.

Here we see an average read speed of 223MB/s and a max of 226.4MB/s. The graph was very tight all the way across the measured range.

The write test had a little ripple that made it look like I was measuring sine waves, but the graph was predictable and in line with other SandForce drives we have tested. Here we see the A-DATA S599 keeping pace with the Vertex 2 drives, the first to feature high IOPS programming.
